I don’t believe that “meeting in the middle” is the correct way to go about it.
We don’t believe in the ends justifying the means so we cannot do something against our ideals in order for the end product of bringing teens closer to yiddishkeit.
Besides, why do we need to show these teens that the only way to have fun is to do it in a not-such-kosher way?
The opposite! Organize bowling, roller skating, etc.. but show that you can have fun in a strictly kosher enviornment!
